石英加速度计离心机试验误差系数显著性分析

提出了一种针对石英加速度计精密离心机试验的显著性分析方法.在多位置方法分离加速度计误差系数时,由于激励不足等试验条件的限制,无法保证高次项系数的标定结果正确.离心机试验利用离心机提供的向心加速度作为仪表的输入,能够标定出高次项系数.为了确定被标定的误差系数均具有可信度,有必要对高过载试验结果进行分析,保留可信的误差系数,证明使用的误差模型无误.由于此方法的通用性,在其他试验条件下的误差分离试验中仍可运用.

Significance Analysis of QFPA's Coefficients Based on Centrifuge Experiment

Some coefficients of the QFPA''s error model could be trustless because of the test technique''s limit. Therefore, it''s necessary to analyze the result and reject the unauthentic coefficients and simplify the error model. A method is put forward to solve this problem based on centrifuge experiment which is one of the error separation tests and taking QFPA as our test object. In this method, F-distribution is taken as the statistics to verify the hypothesis, and an detailed test''s analysis is carried out. As its generality, this method can also be applied to other kinds of methods
